SPOKESHAVE.

SPECIFICATION forming part of Letters Patent No. 395,738, dated January 8,1889. Application filed September 29, 1887. Serial No. 251,088. (No model.)

To all 10700712, it may concern:

Be it known that I, ISAAC? UAMIER, a citizen of the United States, and a resident of Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spokeshaves; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification,and in which Figure l. is an elevation in direction of arrow, Fig. 2, of a spokeshave constructed in accordance with my invention, and Fig. 2 a transverse section of the same. Fig. 3 is a detached sectional perspective view of the cutter-stock. and the clamping-plate for the cutter, illustrating the means for connecting the two together to avoid lateral displacement.

Similar letters of reference indicai'e like parts in the several views.

This invention relates to that classof woodworking planes known in the art as spokeshaves, and the objects of the present improvements are to provide a simple and eiiicient appliance for adjusting the cutter-bit in accurate parallel alignment with the bearing face or sole ol? the body or stock of the shave, and also to furnish means t'orfirmly clamping and holding the cutter-bit to its adjustment.

To enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to more fully describe its construction and operation.

Referring to the drawings, A represents the body or stock of the shave, having any usual shape and provided at each side with a wing or handle, B, by which it is mani nilated.

C is the cutter bit or blade fitting snugly within the throat of the stock, the sides of said throat forming guiding-slides for the cutter-bit in its adjusting movement. At its upper end the cutter-bit is formed with inturned lips c c, that engage sidewise over a collar or head, (I, on the lower end of the adjustingscrew D, which passes through a fixed nut or head, E, at the upper end of the horn or inclined back standard, A, which in the present improvement forms an integral part of the body or stock A of the shave, and, in addition to carrying the adjusting-screw D, also acts as a bed or rest for the body of the cutter blade or hit, as indicated in Figs. 1 and 2.

The back of the horn or standard A is curved, as shown, to form a continuation of the usual curved heel of the shave, and as so curved and inclined forms no obstruction to the use of the shave on recessed or eoncaved work.

The clampingplate G, by which the cutterbit is clamped in its required adjustment, is secured loosely to the stock by means of an attachingscrew, F, which screws into the stock, as shown, and passes through an elongated hole in the bit 0, so that the adjusting movement of the same may take place.

The clamping-plate G, which is of a flat shape, is held from moving in a plane with the cutter-bit, as well as from turning or shifting in such plane, by means of lugs g g, that project in a lateral direction, from its side edges and engage or fit snugly in the opensided recesses u a in the lateral or side walls of the bit-throat, as indicated in Figs. 1 and 3. Such open-sided construction of the recesses a. is material to the present construction, in that it permits of the ready introduction of the clamping-plate into operative position by simply dropping said plate into position. \Vith such ready means for attachment and detachment of the clamping-plate the present construction retains the function of holding the plate G from moving in a plane with the cutter-bit, as above mentioned.

H is a clamping-screw passing through the upper end of the clamping-plate G, with its point resting or bearing upon, the cutter bit or blade C, as shown in Fig. 2. lVith this construction the screw F acts as afulcrum for the clamping-plate G, so that when its upper end is forced outward by the screw H its lower end will be forced against the blade orbit 0, near its ciittiiigeilge, to firmly clamp and hold the same.

By my improved arrangement of parts above described a very substantial and general clamping of the bit is eft'ectedin a quick, simple, and easy manner.

I am aware that prior to my invention the cutting-bits of carpenters planes had their adjustment effected by means of a screw, and also that clamping-plates opera-ted by a set screw were employed to hold or clamp the hit to its adjustment. 1 therefore do not claim either of such constructions, broadly; but

What I do claim as my invention, and desire to secure-by Letters Patent, is

l. The combination, in a spokeshave, of the stock A, having open-sided recesses a a. in the lateral walls of the bit-throat, the clampingplate G, having marginal lugs g g, projecting laterally from its sides and adapted to rest in the recesses a to prevent a movement of the plate G in a plane with the cutter-hit, the holding-screw F, clamping-screw H, and cutter-bit O, essentially as set forth.

2. The combination, in a spokoshave, of the stock A, having open-sided recesses a a in the lateral walls of its bit-throat, the clampingplate G, having marginal lugs g g, projecting laterally from its sides and adapted to rest in the recesses a to prevent a movement of the plate G in a plane with the cutter-bit, the holding screw F, clamping-screw H, adjustingscrew D, and cutter-bit C, essentially as set forth. I

In testimony whereof witness my hand this 17th day of September, A. D. 1887.
